Try this::

SELECT bu.name, 
    max(case when (bb.bill_month='Jan2k19') then bb.package_price else NULL end) as 'first_month_bill',
    max(case when (bb.bill_month='Feb2k19') then bb.package_price else NULL end) as 'second_month_bill',
    max(case when (bb.bill_month='Mar2k19') then bb.package_price else NULL end) as 'third_month_bill'
    FROM bf_users bu
    INNER JOIN bf_monthly_bill bb
    ON bu.id = bb.bf_users_id GROUP BY bu.name;

Output::

name    first_month_bill    second_month_bill   third_month_bill
ABC       500                   200                  500
DEF       300                  (null)                300
GHI       900                   542                  900
JKL      (null)                (null)                200
